Abstract :
We propose and demonstrate a new architecture that combines clock recovery and signal processing functions in a single fiber device. By using parasitic cross-phase modulation of idler wave generated within the parametric sampling gate, rate-variable self-synchronized demultiplexing was demonstrated. Rigorous measurements confirm stable, high sensitivity performance at a maximal rate of 640 Gb/s, even when the input signal is subject to a rapid transient.
